To alfwhom it may concern: 7 Be it known that T, Dennis M. PHILLIPS, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Stainless ]Pastes, of which the followingis a specification.

This invention relates to pastes, and particularly to a paste which will not stain the most delicate fabric and, therefore, can be usedfor the making of artificial flowers.

The general object of my invention is to provide a paste which can be used in making artificial flowers, for millinery and like purposes, and for use with delicate silks, velvets, etc., without staining them or otherwise marring the beauty ,of the artificial flowers, silks, velvets,c'hiffons, etc.

A further object is to form a paste. of this character which will be colorless, stainless, adhesive, pliable and durable and which is practically water-proof.

The paste which I have devised for this purpose consists of a body consist of flour or other starchy material, and preferably consisting of a mixture of rice flour and corn startch, a gum. added in order to make the paste more adhesive, a preservative and a water-proofin material, such as aluminum sulfate, glycerln to check the drying qualities of the gum and which revents the paste from getting hard and sti and an oil of such character that it will not stain but which will reduce the tendency of the paste to dry and also, if possible, give a pleasant spicy odor to the paste.

Preferably my improved paste is made according to the following formula 2-- Boiling water One pint.

Rice flours One-half pound. Corn starch One-quarter pound. Gum arabic One-eighth ounce. Aluminum sulfate One-quarter ounce. Glycerin One dram.

Oil of cloves One-quarter dram. Oil of cinnamon One-quarter dram.

The rice flour and starch are mixed with enough cold water to make a thin paste.- This paste is boiled in boiling water and stirred constantly and cooked over a water bath until it is relatively thick. The paste is then removed from the fire and gum arabic, aluminum sulfate, glycerin, oil of cloves are added thereto and Specification of Letters Patent.

- the paste must not stain or otherwise cinnamon also Patented July it), 1921..

thdroughly mixed therewith. The mass when completed has a pasty consistency, is very adhesive, and will not readily dry out and become brittle, and may be used in collapsible tubes or applied by means of a brush.

As before remarked, this paste is particularly adapted for use in making artificial flowers and for use with delicate silks, velvets, chiffons and other like fabrics, and injure the fabric and must have a certain de cc of flexibility. The reasons for using t e in redients as above described are as follows: he rice flour makes a white, adhesive paste which Will not turn yellow, as wheat or rye flour would do. The corn starch helps to thicken the flour paste and gives it transparency. A paste formed merely of rice flour and corn starch would not have sufficient adhesiveness. This adhesiveness issecured by adding to the mass the gum arabic, while the addition of the aluminum sulfate makes this gum arabic still more-adhesive. Furthermore, this aluminum sulfate acts as a preservative. I am aware that alum itself is used as a preservative, but it is not advisable to use alum in the composition above noted because alum will stain, due to the iron in it while the pure aluminum sulfate will not stain. A ain, the aluminum sulfate makes the artic e practically water-proof, and this is very important. Gum arabic would tend to cause the paste to dry too quickly and, therefore, ll add the glycerin, which keeps the paste from drymg and hardening unduly when exposed to the air. Also, this gylcerin counteracts the stiffness of the paste and thereby keeps the silks and other fabrics, and especially the petals of artificial flowers, pliable. It is also a preservative and gives smoothness to the paste. The oil of cloves and the oil of give smoothness to the paste without oiliness, however, and thereby prevent the staining of delicate articles by the oil, and they are also preservative and are non-driving, and in addition give a pleasant, natural, spic odor to the flowers.

One-fourt of a part of glycerin to onehalf part of gum arabic is ideal, as this amount I find in actual practice checks the drying qualities of the 1." um without mahng the paste too moist. I '1 aluminum sulfate should be approximately twice the amqunt of gum arabic. I do. not wish to be limited to the inclusion of all of the ingredients herewith named, nor to the exact proportions stated, nor to the exact materials,

stated. Thus, in place of the rice flour and corn starch, I may use any finely ground, starchy body, but referably, however, for the reasons stated, I use the rice flour and corn starch. Neither do I wish to be limited to the use of aluminum sulfate as a preservative, though I preferably use this, nor do I wish to be limited to the use of oil of cloves and oil of cinnamon in this composition, though I believe that it is advisable to use these two oils or one of them.

When the oil of cloves and the oil of cinnamon are omitted in this composition, it is necessary to increase the amount of glycerin, and while the paste may be made entirely from rice flour, that is no corn starch used at all, yet where rice flour alone is used, the proportions of the rice flour.

given must be almost doubled, in other words .instead of using one-half pound of rice flour and one-quarter pound of starch, there should be nearly one pound of rice flour used. 0
